5. ARP (ACTIVE ROLL-OVER PROTECTION)
The ARP (Active Roll-over Protection) system is a safety assistant device that minimizes, by controlling brakes and
the engine, the physical tendency of the vehicle rollover during sharp lane changes or U-turns. For the system,
software is added to the existing ESP system and no additional device or switch is needed.
One must note that the ARP system, just as general assistant devices including the ABS, is only a safety assistant
device using the ESP system and its function is useless when the situation overcomes the physical power.
Following picture shows how the ARP compensates the vehicle position by varying each wheel’s braking power to
overcome the physical tendency of the vehicle rollover during sharp turns.

The vehicle driving condition is controlled by the internally programmed logic according to the input signals from
wheel speed sensor, steering angle sensor and lateral sensor.
• During the ARP operation, vehicle safety (rollover prevention) takes the first priority and thus, stronger engine
control is in effect. Consequently, the vehicle speed decreases rapidly, so the driver must take caution for
the vehicle may drift away from the lane.
